thanks guys! and id like some opinions

hello gentlemen, ive been reading posts from here for a year now and wanted to say thanks to all of you for all the great knowledge, and advise you keep giving.
so ill be putting my boat in over at lamberjacks from april to may. i have a cottage with dock over in the bay and fish perch around the islands and wallleye up by middle
that said im looking to load up my tackle box with lures i dont have anything yet i fish walleye with a friend and he has that stuff

my plan is to use 4 line counters and dipsy for trolling and jig in early spring
so my question is what colors should i be concentrating on i cant be spending a ton of money and buy 4 of every color and size

you guys seemed to have this walleye thing down to a science so i was hoping to pick some brains
what do i HAVE to have in the box?

thanks
